Patented Dec.- 30, 1913.

Application led August 10, 1907, Serial No. 387,960. Renewed February 7,1913. Serial No. 746,922.

To all whom it may concern Be it known that I, ARTHUR-Memoir, of

lllarwick, in the county of Kent and State' of Rhode Island, haveinvented certain new is not entirely automatic, for the reason that theknife is not a part of the machine, but requires to be held andmanipulated by the operator during the operation of cutting the races ofthe fabric.

The object of the present invention is to provide a machine which isadapted for the cutting of velvets, and which will be entirely automaticin its operation.

'lo that end the invention consists primarily in mounting the knife on,and making it a part of, the machine, as distinguished from having theknife held and manipulated by the operator.

The invention further consists in so mounting the knife as a part of themachine that the knife will be free to follow any irregularities of theraces, and thus be capable o-f performing its work without theassistance or guidance of an operator.

The invention further consists in providing means whereby a certainforward and backward yielding of the knife will be permitted accordingto the thrust exerted upon it by the fabric during the operation ofcutting, and so that there will be more or vless of a give and takemovement of the knife according to the varying conditions presented.

The invention further consists in providing `means whereby, if the knifeshall ily out of the race, the point of the knife will be moved to aposition above that portion lof the fabric which has been already cut,

and where no harm can result if the knife should come in contact withthe fabric at that point.

rElie invention further consists in the combination, with the knife, ofa stop motion adapted to be automatically operated by the knife to stopthe machine, in case the knife should happen to ily out of the race orto'penetrate the back of the fabric, or become otherwise disarranged.

The invention further consists in the coinbination of two stop motionsfor stopping the machine, one adapted to be operated by the knife andthe other adapted to be operated by the bunch or seam in the endlessfabric.

The invention further consists in the combiiiation of means foroperating either the main forward clutch or the reversing clutch,

and means for determining which of these two clutches shall be operatedthereby.

The invention further consists in certain combinations and arrangementsof parts 'hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side elevation of the machine.Fig. 2 is a side elevation on a larger scale of the forward end of themachine taken from the opposite side, the traveling apron at the bottomof the machine being omitted and the fabric being shown only in part. Fig. 3 is a broken end elevation of the front end of the machine. Fig. -tis a section through the machine on the line -a: of Fig. 1 lookingtoward the front of the machine. Figs.

and 6 are details. Figs. 7 andS are front and rear elevations, and Figs.9 and 10 are opposite end elevations of the knife-holder mounted on itssupporting arbor. Figs. 11, 12, 13, 14 and 15 are details of theknifeholder and its component parts. Fig. 16 is a viewcorresponding to10, but on a smaller scale and showing the knife-arm mounted in theknife-holder.

The machine comprises a suitable frame 1, in which the several operatingparts are mounted. The fabric travels through the machine in the form ofan endless web. The knife 2 is located at the front of the machine, andthe fabric 3, after the race has been cut, is carried down on to atraveling endless apron or lattice 4 at or near the bottom of themachine, where it drops in folds, and in this form is carried by thetraveling apron to the rear of the machine. From the apron at the rearof the machine the fabric is carried up over a feed-roll 5 and down anincline 6. At the foot of this ineline the fabric turns upward and'iscarried over two ixed bars 7, 7 at the top of the frame. Preferably thefabric is left more or less loose at the point where its diioo passedaround two intermediate idler-rolls` 13a, 13b, and thence to thefeed-roll 14. As will be seen, by the employment of the two idler rolls13, 3b, arranged Vas shown in the drawings, in connection with thetension-roll 12, the fabric is caused to extend around nearly the entireperiphery of the drag-roll 13, thereby increasing the friction betweenthe fabric and said roll, and enabling said roll to be a plain steelroll, instead of a rubber-covered roll. The roll 13b also serves tolocate the fabric for presentation to the p knife.

In passing from the idler-roll 13b to the feed-roll 14 the fabric passesbeneath the knife 2. From the feed-roll 14 the fabric passes to thetension-roll 15, thence downward between a pair of supplementalfeedrolls 16, 17, the feed-roll 16 being beltdriven, and the feed-roll17 being an idlerroll, and thence down on to the traveling apron 4 abovereferred to.

The necessary tension at the cutting point is produced by means of therolls 13 and 14. The feed-roll 14 is positively driven, while thedrag-roll 13 is provided with a friction device whereby a friction ordrag may be put on said roll.

The main driving shaft 19 is provided with a pulley 2O driven by a belt21 from an over-head counter-shaft. On the opposite end of the drivingshaft 19 is a pulley 22, from which a belt 23 extends to a pulley 24 onthe left hand end of the positively driven feed-roll 14. On the drivingshaft 19, adjacent to the main'driving pulley 20, is a pulley 25, fromwhich a cross-belt 26 extends to a loose pulley 27 on the feed-roll 14.The pulley 27 is a two-step cone-pulley, and from the smaller step ofsaid pulley a belt 28 extends to aV pulley 29 on the right hand end ofthe drag-roll 13.

In the present machine thedrag-roll 13, instead of being of the samediameter as the feed-roll 14, is of considerably larger diameter, and assaid drag-roll becomes a feed-roll for the reverse feed, it is desirabletlc correspondingly reduce the speed of said drag-roll 13 whenoperating' as a feed-roll during the reverse feed, and for this purposethe step of the pulley 27 over which the belt 26 passes is ofconsiderably larger diameter Vbelt 38 extends to a hand end of thefeed-roll 5. From the pul- 4Contact with the pulley-flange.

than the pulley 25, and the pulley 29 on the drag-roll 13 is alsoconsiderably larger than the smaller step of the pulley 27 over whichthe belt 28 passes.

- On the left hand end of the drag-roll 13 are two pulleys 30 and 31, asshown in Fig. 2. From the pulley 30 a belt 32 extends around a pulley 33on the left hand end of the supplemental feed-roll 16. From the pulley31 a belt 34 extends to a pulley 35' on the left hand end of the roll10. On the right hand end of said roll l0 are two pulleys 36 and 37.From the pulley 36 a pulley 39 on the right ley 37 a belt 40 extends toa pulley 41 on a stud 42, on which stud is a second pulley 43 connectedto said pulley 41, and from which pulley 43 a cross-belt 44 extends to apulley 45 on a shaft 46 at the rear end of the machine. Said shaft 46 isthe feed-shaft for the endless traveling apron 4. In the drawings abelt-tightener 40a is shown for tightening the belt 40.

The pulley 22 on the driving shaft 19 is loose on said shaft, but isadapted to be connected with said shaft" by a suitable clutch mechanism,preferably a friction-clutch as shown in the drawings. This clutch maybe of any desired construction, and as it forms no part of the presentinvention, the detailed construction of the clutch shown need not bedescribed. It will be understood that when the pulley 22 is connectedwith the driving-shaft 19, the fabric will be fed through the machine,and when the pulley 22 is disconnected from the shaft 19, the feed ofthe fabric will be stopped. The clutch mechanism as a whole isdesignated as 47 in the drawings, and said clutch mechanism is adaptedto be operated by the lever 48. p

In machines of this character it is desirable that when the drivingpower is disconnected for the purpose of stopping the machine, themachine should be quickly brought to a full stop, and so as to promptlystop the feed of the fabric. For this purpose a brake-mechanism isapplied to some part of the feed mechanism to quickly stop the Vfeed ofthe fabric whenever the driving power is disconnected.

In the arrangement shown the brake is applied tothe drag-roll 13, orrather to the pulley 30 on said roll. This brake may be of any suitableconstruction, and in the drawings is shown as comprising a brake-shoe 49pivoted to a braclet secured to the frame,

which brake-shoe is adapted to be forcedV into contact with the innersurface of the flange of the pulley 30 by means of a coilspring 50. Y p

The brake-shoe 49 is normally, or Vwhile the machine is in operation,latched out of Connected to the free end of the brake-shoe is a verticalbar 51 which extends downward and is supported and guided by a bracket52 extending from the frame of the machine. Adjustably secured to oneside of this bar 51 is a notched block 53 adapted to engage, or beengaged by, the forward end of a movable bar 54. One end of the springv50 is connected to said bar 51, the other end of said spring beingconnected to a bracket 55 on the frame. Then the machine is running thebar 51 is latched and held in its upper position, and so as to hold thebrakeshoe 49 out of contact with the flange of the pulley 30 by the endof the movable bar 54 engaging the notched block 53. Vhen, however, saidmovable bar 54 is moved rearward by any suitable means, the bar 51 isthereby disengaged and is pulled downward by the spring 50, therebyforcing the brakeshoe into contact with the ange of the pul ley 30 andstopping the feed of the fabric. In the machine shown means are providedfor automatically throwingout the clutch 47 and for automaticallyapplying the brake 49, which means will be hereinafter de-V scribed.

The means for releasing the brake and starting the machine to feedforward the fabric after the machine has been stopped and the brakeapplied will be next described. A foot-treadle 5G extends across thefront of the machine where it may be conveniently operated. This treadleis secured by means of arms 57, one on each side of the machine, to arock-shaft 58, which extends across the machine and is arranged to turnin bearings in the frame. Connected to this rock-shaft are two weights59,.one on each side of the machine, which act to normally hold thetreadle 56 in its upper position. Secured to the rock-shaft 58 is an arm60, to which is connected one end of a connecting rod 61, the other endof which rod is connected to one arm of a bellrrank lever G2 which ispivoted on the frame, as shown in Fig. 2. The other arm of thisbellcrank lever is provided with a friction-roll (S3, which underliesthe lower end of the vertical bar 51 which is connected to thebrake-shoe. When the'bell-crank lever 62 is rocked, by depressing thetreadle 56, one result will be to lift the brake-shoe 49 out -of contactwith the ange of the pulley 30 resent machine the reversing clutch to beclutch-lever 48, instead of being a permanent connection, is madedetachable, but when the connection between said arms 65 and 48 is madeand the treadle 5G is depressed, the further result will be that the arm65 will be rocked, and this in turn will serve to pull inward the lowerend of the clutch-lever 48, and thus throw in the clutch 47 and connectthe pulley 22 tothe driving shaft 19.

Pivoted to the clutch-lever 48 is a latchbar 68 provided with a shoulderG9 adapted to engage the bracket 70, through a slot in which bracket theend of the latch-bar 68 extends. lVhen the clutch 47 is thrown in toconnect the pulley 22 with the shaft 19, the upper end of theclutch-lever 48 is moved away from the bracket 70, and so as to draw thelatch-bar G8 outward and into a position where the shoulder 69 on saidlatch-bar will engage said bracket, and thereby latch and hold theclutch in its engaged posit-ion. The weight of the latchbar (38 willordinarily be sufficient to cause said bar to fall down and engage thelatch. lf desired,-however, a spring may be employed for this purpose.

It is desirable in machines of this character to provide means tor-everse the machine and the feed of the fabric, in order that if theknife should fly yout of the race, or any other accident happen, thefabric may be run back a short distance for Jthe purpose of reinsertingthe knife in the race. This reversal of the machine is effected by meansof the cross-belt 26 running on one of the steps of the cone-pulley 27on the feed-roll 14. rlhis cross-belt 26 is driven by the pulley 25,which is loose on the main driving shaft 19, but which is provided witha clutch 71 adapted to be operated by a lever 72 for clutching saidpulley to said driving shaft. In the present machine, as hereinbeforestated, this reversing clutch 71. as well as the forward clutch 47, isoperated by the foot-treadle 55, said reversing clutch` like the mainstarting clutch, being operated from the rock-shaft GG, means beingprovided for determining which of these two clutches will be operatedwhen the foottreadle is depressed.

Mounted on the rock-shaft 6G is a sliding collar 73 having an arm 74projecting rearwardly therefrom, which arm carries a vertical rod 75,which rod partakes of the sliding movements of said collar 73. Securedto the rock-shaft G6 are two rearwardly ex tending arms 75 and 77 whichserve as guides for the rod 75 as it is moved upward or downward by saidsliding collar. The sliding movements of the collar 78 and the rod 75are effected by means of a handlever 78, pivoted to the frame at thefront end of the machine, through the following connections. Abell-crank lever 79 is pivoted to the frame, the horizontal arm of whichlever is provided with a projecting pin 80 adapted to enter a groove inthe sliding collar 73. The vertical arm of said bell-crank lever isconnected by means of a rod 81 with the lower end of the handlever 78.

Connected to the end of the clutch-lever 48 is a latch-bar 82, the freeend of which latch-bar is supported by a pin 83 projecting from theframe, which pin extends through a slot in said latch-bar, as shown inFig. 4. Said latch-bar 82 is provided with a suitable notch to form ashoulder 82a adapted to be engaged by the upper end of the sliding rod75. To the lower end of the reversing clutch-lever 7 2 is connected alatch-bar S4, which extends across the machine, said latch-bar beinglikewise provided with a suitable shoulder 84a adapted to be engaged bythe lower end of said sliding rod 75. In order to provide for theswinging movement imparted to the slidingrod 75 by the rocking of theshaft 66, it is desirable to provide a swivel connection between the arm77 and the latch-bar 84. Loosely mounted in the end of the arm 77 is ahollow stud 85, the lower end of which is forked to receive the end ofthe latchbar S4, said latch-bar being connected to the forked end ofsaid stud by means of a crosspin 85a. The hollow stud is held in placein the arm 77 by means of a nut 86 which engages the upper end of saidstud. As will be understood, the lower end of the sliding rod 75projects through said hollow stud, and so that the lower end of said rodmay be moved into engagement with the shoulder 84EL on the latch-bar 84.

Vith the construction above described the operation of starting orreversing the machine is as follows: lVhen the hand-lever 7 S is pulledforward into the position shown in Fig. Q, the sliding collar 73 and thesliding rod 75 will be moved upward, so as to bring the upper end ofsaid rod into engagement with the shoulder on the latch-bar S2. vWiththe sliding rod held in this position, the foot-treadle is depressedwhich will serve to turn the rock-shaft 66, thereby giving a. swingingmovement to the rod 75, which movement will serve to actuate thelatch-bar 82 and the clutch-lever 43 to throw the clutch 47 int-oengagement. YVhen now it is desired to reverse the machine, thehand-lever 73 is thrown backward, which will serve to move tie slidingcollar and the sliding rod downward, and so as to move the upper end ofsaid rod out of engagement with the latch-bar 32, and to move the lowerend of said rod into engagement with the latch-bar 84. By now depressingthe foottreadle, and thereby turning the rock-shaft 66, a. swingingmovement will be given to the sliding rod 75 which will serve to move ithe latch-bar 84 and the lever 72 to throw in the reversing clutch 71.Vith the position of the parts shown in Fig. 4, both the clutch 47 andthe clutch 71 are out of engagement and the machine is at rest. Thesliding rod 75, however, is shown in its upper position and inengagementwith the latch-bar 82, and so that by the depression of thefoot-treadle, the clutch 47 will be thrown'into engagement. In order topermit the necessary swinging movement of the rock-shaft66 to operatethe latch-bar S2, without at the same time operating' the latch-bar 84,said latch-bar 84 is provided with an elongated slot 34b through whichthe cross-pin 85a passes, as shown in Fig. 4.

As above stated, both of the supplemental feed-rolls 10 and 16 are beltdriven rolls, both of said rolls being driven from the drag-roll 13. Asshown in the drawings, the pulley 35 on the feed-roll 10 is somewhatlarger than the pulley 31 on the drag-roll,

and so that said feed-roll will be rotated at a somewhat slower speedthan the drag-roll,

and will thus serve to put a certain amount of drag on the fabric as itapproaches said drag-roll. In the case of the feed-roll 16, however, itis desirable that said roll should rotate at a higher speed than thedrag-roll 13, in order to put a pull upon the fabric, and for thispurpose the pulley 33 on said roll 16 is shown as considerably smallerthan the pulley 30 on the drag-roll.

Vhile it is desirable that the feed-roll 16 should rotate at a higherspeed than the drag-roll 13 and the feed-roll 14 during the forward feedof the fabric, it is not desirable that said roll 16 should rotatefaster than the feed-roll 14 during the reverse feed of the fabric,because in such case the effect of said roll 16 would be to put slack inthe fabric between said roll and the main feedroll 14, which would beobjectionable. In order to prevent such objectionable operation, andalsor to transform said feed-roll 16 from a roll exerting a forward pullon the fabric to a roll exerting a backward pull on the fabric, thefollowing means are provided.

The pulley 33, instead of being fast on the feed-roll 16, is loosethereon, and adapted to be connected with said roll during the forwardfeed of the fabric by means of a pawl and ratchet. In Vthe constructionshown the ratchet 87 is formed on the pulley 33, and the pawl SSiscarried by the disk 16a secured to the roll 16,'the arrangement of saidpawl and ratchet being such that when the dragroll 13 is rotated to feedthe fabric forward the roll 16 will be rotated in the same ydirection bymeans of said pawl and ratchet. drag-roll is rotated in the backwarddirection for the reverse feed of thefabric the ratchet-teeth on thepulley will ride under TWhen, however, the

the pawl carried by the roll, and so that said roll will be free to beturned by the pull of the fabric.

In order to put a drag on the fabric during the reverse feed, it ispreferred to provide means for braking the feed-roll 16 during suchreverse feed, and in the drawings a brake is provided for this purpose,which brake is adapted to be automatically operated in the followingmanner: Pivoted to the bracket at the left hand side of the machine inwhich the feed-roll 16 is mounted is a brake-lever 89, the rear end ofwhich is suitably curved to form a brake 90 adapted to engage the outersurface of a flange 91 formed on the disk 16a secured to the roll 16. Tothe forward end of the lever 89 is connected one end of a spring 92, theother end of which spring is attached to the frame or some fixed part ofthe machine, being shown in the drawings as connected to the pivot ofthe hand-lever 78, which said spring normally acts to pull down theforward end of the lever 89, and thus to apply the brake 90 to thefeed-roll 16. The application of said brake 90 is controlled by thehand-lever 78. The lever 89 lies in the path of a pin 93 projectinghorizontally from said lever 78, and said lever 89 is provided with arecess 94, the construction being such that when the hand-lever 78 ispulled forward the forward end of the lever 89 will be held in a raisedposition by the engagement therei with of the pin 93, but when saidlever 78 is thrown rearward the forward end ofthe lever will, by reasono-f the recess 94, be pulled downward by the spring 92, therebyautomatically applying the brake 90. It is preferred when the lever 78is pulled forward to latch said lever in its forward position, and forthis purpose the lever 89 is provided with another recess or notch 95adapted to engage the pin 98fwhen the lever 78 is pulled forward, asshown in Fig. 2.

The machine shown in the drawings is provided with a mechanical stopmotion for automatically stopping the machine when the bunch or seam inthe endless fabric approaches the knife. As above stated, when theclutch 47 is thrown in, said clutch is latched in engagement by thelatch 68 engaging the bracket 70. Connected to the upper end of theclutch-lever 48 is a spring 96, the other end of which spring isconnected to a fixed support 96a. When the clutch-lever 48 is moved tothrow in the clutch 49 the spring 96 is put under tension, and willoperate whenever the latch 68 is disengaged to automatically throw outsaid clutch. For the purpose of automatically stopping the machine bythe bunch or seam in the fabric, means adapted to be actuated by saidbunch are provided for disengaging the latch v68. Extending across themachine above the fabric is a rock-shaft 97 which carries a fiatleaf-spring 98, which spring normally lies in engagement with thefabric. The present constructionis such that said leaf-spring 98 islocated in proximityto the drag-roll 13, and in a position where itengages the fabric as it passes over said drag-roll.

Pivoted to the bracket 99 is a lever 100 provided 'at one end .with aprojection 101 adapted to be engaged by a latch formed on the end of thearm 102 carried by the rockshaft 1022i. The opposite end of said lever100 is connected by a link 103 with an arm 104 carried by a rock-shaft105 suitably mounted in fixed supports. The rock-shaft 105 is providedwith an upwardly projecting toe 106 arranged to normally underlie oneend of a pivoted lever or tappet 107 pivoted on the bar 54. The tappet107 is provided with a notch 107a adjacent to the toe 106 when the partsare in normal position. Pivoted on the frame at 108 are two levers 109arranged side by side. As the construction Yand operation of these twolevers and their connecting and cooperating parts are the same, it willbe suflicient to describe the construction and opera-tion of one of saidlevers. Mounted on the shaft of the driven roll 10 is an eccentric 110which is connected with the upper end of the lever 109, whereby saidlever is vibrated back and forth at. each revolution of said shaft. Thebar 54 extends lengthwise of the machine, said bar being pivotallyconnected at one end to the pivoted link 111, and being connected at itsother end to one arm of a bellcrank lever 112, which bell-crank lever isadapted to be operated by said bar 54. The tappet 107 pivoted on the bar54 is normally held in a horizontal position bythe engagement therewithof the toe 106, and when thus held in a horizontal position the forwardend of said tappet will be out of the path of the vibrating` lever 109.The other arm of the bell-crank lever 112 projects through an inclinedslot or cam-slot 113 in the latch-bar 68 pivoted to the clutchlever 48.Connected to the lower end of the arm 102 is a rod 114, the other end ofwhich rod is connected to a lever 115 secured to the rock-shaft 97.

The operation of the automatic stop motion above described is asfollows: As the bunch or seam in the fabric passes beneath thespring-arm 98 it will serve to rock the shaft 97, and thereby disengagethe latch 102 and release the lever 100. The rear end o-f said lever 100is weighted or is suiiiciently heavy so that when released by theunlatching of the latch 102 the rear end of said lever will falldownward, thereby raising the forward end of said lever. The raising ofthe forward end of said lever 100 will, through the link 103 connectedto the arm 104 on the rock-shaft 105, serve to rock said rock-shaft,which will cause the toe 106 to be moved from beneath the tappet 107,and cause the forward end of said tappet to be moved into the path ofthe vibrating lever 109. By the action of said lever the bar 54 will bemoved rearward, turning the bell-crank lever 112 which, by reason of thecam-slot 113, will serve to unlatch the latch 68 and thereby permit theclutch 47 to be thrown out by the spring 96. The rearward movement ofthe bar 54 serves to unlatch the bar 51 and thereby cause the brake tobe applied by the action of the spring 50.

The construction and arrangement o-f the knife-holder, whereby the knifeis made a part of the machine, together with an automatic stop motionfor automatically stopping the machine when the knife runs out 0f therace or projects through the back of the fabric, or is otherwisedisarranged, will next be described.

Slidably mounted on the bar 116 which extends across the front of themachine is a sleeve 117, the aperture in which is preferably square incross-section to t said bar. Projecting downwardly from said sleeve is aU-shaped bracket 118, in which the knifeholder 119 is pivotally mounted.The knifeholder is composed of two part-s, 120 and 121, for a purpose tobe hereinafter described, but the knife-holder as a whole is pivoted inthe bracket 118, so as to be capable of turning about a horizontal axis.As shown in the drawings, the part 120 of the knife-holder is mountedbetween two horizontal screws 122, which screws are preferably providedwith conical points adapted to take into corresponding conical recessesformed one on each side of *the knife-holder. lV ith this Constructionthe knife-holder is adapted to swing toward and from the front of themachine.

The part 121 of the knife-holder is provided with an elongated shank 123provided with two enlargements 123 and 1231], and the part 120 beingbored and counterbored to receive said shank and enlargements, as shownin Fig. 12. A torsion-spring 124, adapted to surround the shank 123, hastwo collars 124a and 124b secured one to each end of said spring, saidcollars being adapted to surround the enlargements 123fL and 123brespectively. The collar 124D and the shank 123 at the enlargements 123bare provided with transverse holes 125 and 125a through which is passeda transverse pin 126, whereby the lower end of the torsion-spring 124 ismade fast to the shank 123. rlhe collar 124a and the shank 123 at theenlargement 1232L are likewise provided with transverse holes 127 and127, through which is passed the transverse pin 128. The hole 127a inthe shank is made of somewhat larger diameter than the hole in thecollar, as shown in Figs. 13 and 14, whereby a slight turning movementof the vertical pivot formed by the shank may be given tothe part 121 ofthe knife-holder by the action of the torsion spring 124. lVith thisconstruction the part 121 of the knife-holder, when permitted to beacted upon by said spring, will normally stand at a slight angle withrelation to the part 120 of said holder.

For the purpose of limiting the extent of the forward and back swingingmovements of the knife-holder, an arm 129 is rigidly secured to one ofthe legs of the bracket 118. The upper end of said arm is provided witha U-shaped slot 130 into which projects the pin 131 projecting fromtherpart 120 of the knife-holder. The engagement of said pin 131 withthe opposite walls of the slot 130 serves to limit the forward andbackmovements of the knife-holder. y

Means are provided for automatically swinging the knife-holder backwardon its horizontal pivot whenever such movement is permitted, such meanscomprising a spring-pressed plunger 132, which said plunger is actedupon by a spring 133. It is desirable to adjust thetension of saidspring in order to regulate the amount of thrust upon the knife whichwill serve to overcome the force of said spring, and for this purpose anadjusting screw 134 is provided, which said screw is mounted in an ear135 projecting downward` from the sleeve 117. Said adjusting screw Visprovided` with a shoulder 136 against which one end of the spring 133abuts. By turning said adjusting screw, therefore, the tension of saidspring may be adjusted.

The part 121 of the knife-holder is provided with two transverseslots137 and 138 arranged at right angles to each other, the slot 137being adapted to receive the shank of the knife-arm, and the slot 138being adapted to receive the trunnions or projecting pins 139 on saidknife-arm.

rIhe purpose of constructing the knifeholder in two parts,`with the part121 capable of turning on a vertical axis with relation to the part 120under the action of the spring 124, is to cause the knife-arm and knife,when the knife leaves the race, to be thrown to one side, as for exampleto the right, and thus above the portion of the fabric which has beenalready cut. lVith this construction it is desirable to provide meansfor conveniently returning the part. 121 and the knife-arm and knifecarried thereby to their normal positions for the purpose of renteringthe knife in the race, and for this purpose the part 121 of theknife-holder is provided with a projecting pin 140 bent to form acamsurface. Mounted on the sleeve 117 is a second sleeve 141 adapted tohave a limited turning movement on the sleeve 117. Said sleeve 141 is toengage the bent pin or cam-projection '140, and so that by turning saidsleeve 141 by hand, the engagement of said pin 142 with said bent pin orcam-projection will serve to turn the part 121 of the knife-holder andthe knife-arm carried thereby, and return them to their normal position,where they may be held until the knife has been properly rentered in therace. In order to limit the movement of the sleeve 141 said sleeve isprovided with a slot 143, and a pin 144 projecting from the sleeve 117enters said slot and is adapted to engage the end walls thereof.

In cutting the iirst race the backward thrust upon the knife is greaterthan in cutting the successive races in what is known as right-racecutting. For this reason, among others, it is desirable to hold theknife-holder against turning on its horizontal axis toward the front ofthe machine during the cutting of the first race. For this purpose thefollowing means are provided. The part 12() of the knife-holder isprovided on one side at its upper end with an oifset 145 in which isformed an inverted V-shaped slot 146. Projecting'from the sleeve 141 isa pin 147, the end of which is adapted to enter said slot 146. The partsare so arranged that when the sleeve 141 is turned to bring the part 121of the knifeholder into proper position for entering the knife in therace, said pin 147 will be moved to the apex of the slot 146, and aslong as said sleeve 141 is held in this position the knife-holder willbe prevented from turning on its horizontal axis either forward orbackward, by reason of the engagement of the pin 147 with the walls ofthe slot 146 at the apex thereof.

IVith the above construction whenever the knife flies out of the racethe forward thrust of the knife will be relieved, whereupon the spring133 will act to turn the knife-holder about its horizontal axis towardthe rear of the machine. On the other hand, whenever the thrust on thelknife is increased sufficiently to overcome the tension of said spring133, as will be the case, for instance, when the knife projects throughthe back of the fabric, or when the knife enters a slip race, instead ofa right race, the knife-holder will, by 'such increased thrust, beturned about its horizontal axis toward the front of the machine andagainst the act-ion of said spring. It isdesirable when either of thesethings happens that the machine shall be stopped, and means are providedfor automatically stopping the machine in. either case, such meansconsisting of an electric stop motion which will be next described.

Extending across the machine at the front end and parallel with the bar116 is a bar 148. As shown in Fig. 2, one wire 149 of an electriccircuit is connected to the bar 116 and the other wire 150 is connectedto the bar 148. Secured to the U shaped bracket 118, but insulatedtherefrom, is an arm 151 to which is secured the wiperspring 152, whichsaid spring rides upon the bar 148 and thus maintains electrical contacttherewith in any position of the knife-holder transversely of themachine. In the construction shown said arm 151 is connected to thebracket 118 by the same stud or bolt 153 that secures the arm 129 tosaid bracket, and so that said arm 129 is in electrical communicationwith said arm 151, both of said arms being insulated from the bracket118, and being thus insulated from the bar 116. The pin 131 carried bythe knife-holder is in electrical communication with said bar 116, andit will therefore be seen that whenever said pin comes in Contact witheither the front or the rear wall of the slot 130 in the arm 129, theelectric circuit will be closed, said pin 131 constituting thecircuit-closer.

As shown in the drawings, the wire 149 connects with one pole of thebattery B. Leading from the other pole of the battery is a wire 154,which may, if desired, lead directly to the electro-magnet E, with whichelectro-magnet the wire 150 connects. It is preferred, however, toprovide means for breaking the electric circuit after it has beenclosed, and for this purpose the wire 154, instead of leading directlyto the electro-magnet, is connected with a binding screw 155 carried bythe latch-lever 68. Secured to the frame of the irachine is a springelectrode 156 adapted to be engaged by the electrode 155 whenever thelatch-lever is moved to engage the clutch 47. A wire 157 connects theelectrode 156 with the electro-magnet E. IVith this construction, aswill be seen, whenever the machine is stopped7 either automatically orotherwise, the movement of the latch-lever 68 to the left in Fig. 4 willserve to move the electrode 155 out of contact with the electrode 156,thereby breaking the circuit. It will be understood that the electrode156 is insulated from the frame of the machine.

The armature 158 of the electro-magnet E is pivoted at 159 to the frameof the machine, and the outer end of said armature is connected by alink 16() to the arm 104 of the rock-shaft 105.

'IVith the above construction it will be seen that the electric circuitwill be closed whenever the pin 131 comes in contact with either wall ofthe slot 130, as when the knife leaves the race, or when the knifeprojects through the back of the fabric, and that when said circuit isclosed and the electro-magnet E thereby energized, the pulll of thearmature 158 will move the link 160 upward, and thereby move the toe 106out from beneath the tappet 107, as in the case of the mechanical stopmotion above described, and thereby cause the clutch 47 to be automatically thrown out, and the brake L t9 to be automatically applied.

It will thus be seen that the-machine is provided with two automaticstop motions, one a mechanical stop motion adapted to be operated by thebunch or seam in the fabric, and the other an electric sto-p motionadapted to be operated by the knife or knife-holder, whenever the knifebecomes displaced from its proper position in the race to be cut. Itwill be further noted that these two stop motions are connected t0-gether, and so that each of said stop motions will serve to operate theclutch 47 and the brake 59. By reason of this connection of the two stopmotions it is necessary or desirable to provide means whereby theoperation of one stop motion will not be prevented by the other, andwhereby, on the other hand, the operation of one stop motion will notoperate the other. As shown in the drawings, the link 160 is providedwith an elongated slot for the reception of the pin 161, which serves toconnect said link with the arm 104. So also, the link 103 is providedwith a slot fo-r the reception of the pin 169., which connects said linkwith the lever 100. lith this construction, as will be seen, the arm 104of the rock-shaft 106 may be moved upward by the link 103, under theaction of the mechanical stopmotion, without any corresponding move- Yment of the link 160, whereas, on the other hand, said arm 104e may bemoved upward by the link 160, under the action of the electric stopmotion, without any corresponding movement of the link 103.

It will be seen that in the machine above described the knife forms anoperative part of the machine, and so that the machine thereby becomesentirely automatic in its operation, there being nothing for theoperator to do with respect to the cutting of the fabric except to enterthe knife in the proper race at the commencement of the cuttingoperation.

It will be further seen that with the construction shown, while themachine is thus entirely auto-matic, the liability of injury to thefabric is reduced to a minimum. If the knife flies ont of the race, orpenetrates the back of the fabric, or enters a wrong race, the machinewill be automatically stopped, while in case the knife flies out of theracc it will be moved in a direction to carry it above that portion ofthe fabric which has already been cut where it can do no harm, even ifit comes in contact with the fabric before the machine is stopped.

As will be seen, the mounting of the knife so that it has a forward andback yielding or give and take movement, according to the amount ofthrust exerted upon it by the fabric or the amount of resistance offeredby the fabric, as well as its capacity to follow any irregularities inthe races, causes the operation of cutting with the knife thusincorporated as a part of the machine to closely resemble the operationof cutting when the knife is held by the operator, and renders theautomatic cutting of the fabric, not only possible, but entirelypractical, which has not heretofore been the case.

In addition to the stop motion for antomatically stopping the machine incase of any accidental displacement of the knife, the machine alsoembodies a stop motion for automatically stopping the machine when theseam or bunch in the fabric approaches the knife, and these two stopmotions are so arranged and combined that the operation of one stopmotion will not be interfered with by the other, and that each may beoperated without operating the other.

By operating the reversing clutch by a foot-treadle, said reversingclutch may be held in engagement during the reverse feed of the fabricby the foot of the operator, thereby leaving both hands free tomanipulate the cloth or the knife, or to perform any other operationsthat may be necessary or desirable during such reverse feed. Sucharrangement also makes it possible to operate both the main clutch andthe reversing clutch by one and the saine device, with means fordetermining which of said clutches is to be operated thereby, which is afurther convenience in the practical operation of the machine.

I ain aware that in machines for cutting pile fabrics, in which a seriesof rotary cutters arranged to cut the pile from the outside of the raceare employed, such rotary cutters have been mounted on and have formeda. part of the machine, but such machines are of a different type fromthat to which my invention relates, operate in a different manner, andare not adapted for the cutting of velvets.
